. removed before the contents of the tube or receptacle can be extruded, and as the caps are relatively small they are frequently dropped or misplaced by the user and lost, so that the remainder of the contents of the tube is exposed to the air and dust and is thereby rendered unfit for use.

The principal object of the present invention is to provide retaining means for the screw cap of such a tube or receptacle which will allow the cap to be removed and replaced in the usual manner but which will permanently unite the cap and tube so as to prevent loss or misplacement of the cap during dispensing of the contents of the tube.

In the accompanying drawings, certain embodiments of the invention are illustrated by way of example, and in such drawings:

Fig. 1 is a fragmentary front elevation of a collapsible tube or container showing the closure or cap therefor in vertical section:

Fig. 2 is a fragmentary side elevation of a collapsibletube having a'cap construction of a modified form:

Fig. 3 is a fragmentary elevation at right angles to Fig. 2 showing the cap in closed positionand in vertical section:

Fig. 4 is a view similar to Fig. 3 but with the cap .o-pen:

Fig. 5 isa view similar to Fig. 3 but showing a further modification:

Fig. 6 is a similar view showing a stillfurther modification:

Fig. 7 is a perspective view of an element employed in constructing the device of Figs. 2, 3 and 4: and

Fig. 8 is a perspective of a device forming an element of the structure of Fig. 6,

Referring to the drawings, the numeral 1 indicates the upper portion of a collapsible tube, can or other container having a neck 2 which is externally screw-threaded at its upper end'at 3. The screw-threaded upper end of the neck is of somewhat larger diameter than the smooth lower part thereof, providing a stop shoulder 4. A cap 5, of substantially cylindrical form closed at its upper end, is provided for closing the end of the neck 2. This cap is internally screw- 1923. Serial No. 649,889.

threaded at its upper portionas indicated at 6 for engagement with the screw threads 3. The lower part of the cap forms an apron 7 which is concentric with the lower part of the neck 2 and which is spaced from the latter to provide an annular chamber 8. The outerrim' of the'cap "may be knurled as at 9 for convenience in manipulation.

A ring 10, conveniently formed from wire, snugly encircles the smooth lower part of the neck 2 so that it may not he slipped off past the shoulder 4. This ring, however, is free to slide axially of the neck. At diametrically opposite points the ring 10 is provided with projections 11, 12 respectively conveniently formed by bending the wire of which the ring is constructed. These projections pass loosely through openings 13, 14 in the depending lower portion 7 of the cap and constitute pivot members. The

outer ends of the pivot members 11, 12 may be enlarged as shown at 15, 16 to prevent gllieir withdrawal from the cap after assem- The cap is screwed onto the neck of the container in the ordinary manner and when it is desired to dispense material from the container, the cap is unscrewed, the ring 10 gradually moving up toward the shoulder 4. lVhen the cap is completely unscrewed, it may be swun to one side about the axis furnished by fire pivot members 11, 12.

These pivot members together with the ring 10 thus prevent complete separation of the cap from the neck of the container so that loss of the cap is impossible.

Referring to Figs. 2, 3 and 4, the container is indicated at 18, having the neck 19 screw-threaded at 20 for the reception of a cap 21, the cap being furnished with an internaly screw-threaded portion 22 for engagement with the threaded part of the neck.

A ring 23 encircles the part 22 of the cap, being seated in a circumferential groove therein. This ring is conveniently formed from wire which is bent at the points 24, 25 to provide the depending legs 26, 27 respectively. These legs are again bent at"their lower ends to form the inwardly directed pivot members 28, 29. These latter members are received in vertical slots 30 disposed diametrally opposite each other in the neck 19 of the container.

When the cap is closed the parts occupy the position shown in Fig. 3. In unscrewin which \the container is indicated at 3l,

ing the'cap, the latter turns freely within the ring 23 until it occupies the position shown in Fig. 4 with the ends 28, 29 of the ring located in the upper portion of the grooves 30. In this position the cap may be swung to one side about the axis of the members 28, 29.. i

In Fig. 5 a further modification is shown having a neck 32. A cap33 provided with a depending portion 34 cooperates with the neck of the container. nally screw-threaded at 35 for engagement with the threaded neck of the; container and is provided with a radial flange 36 spaced from the head or top member of the cap. A ring 37 encircles the part 34 of the cap and is free to slide axially between the flange 36 and the head or top member of the cap. This ring is furnished with depending legs 38, 39 bent inwardly attheir lower ends to provide the pivot members 40, 41 respectively which engage bearing openings in the outer surface of the neck 32. This arrangement is operated in substantially the same manner as that just described.

In Fig. 6 the container is indicated at 42 and the cap at 43. The cap is internally screw-threaded for engagement with the threads 44 at the top of the neck 46 of the container. The lower portion of the neck is smooth and is encircled by a ring having the upwardly directed arm 47 which is disposed between depending ears 48 projecting from the lower surface of the cap. A pivot pin 49 extends through these ears and through the upper end of the arm 47.

' The cap may be unscrewed in the usual manner, raising the ring 45 with it until the cap is disengaged from the screw threads of the neck. The cap may then be swung to onesideabout the axis of the pivot pin 49 which prevents loss or misplacement of the cap relatively to the container.

I claim: v v 1. A receptacle having a screw threaded The cap is intertop and internally screw threaded at its upper portion for engagement with the neck, a portion of the cap being the lower unthreaded and of a diameter larger than the neck, a ring encircling the neck and dis-- posed within the lower part of the cap, and means pivotally connecting the ring and cap. 4

3. A receptacle having a screw threaded neck, a cap rovided with an internally screw threaded portion engageable with the threads of the neck and having a lower portion spaced from the' neck, and'a' ring encircling the neck and axially movable to a limited extent thereon, said ring having diametral projections constituting pivots engagmg openings in the dependlng portion of the cap.

4. A receptacle provided with a neck having a smooth lower portion and an exter nallyscrew threaded upperp-art of "larger -diameter, a hollow cylindrical cap closed at its upper end and internally screw threaded adjacent to said end for'engagement with the threaded part of the neck, the lower part of the cap being concentric with the smooth portion of the neck but spaced therefrom to I leave an annular space th'erebetween, a ring within said space closely encircling the lower portion of the neck but sliding axially thereon, and pivot membersprojecting diametrally from the ring into openings in the lowerpart of the cap.
